An indirectly accessed disk storage device comprises a rotating disk memory coupled to an intelligent disk controller. The intelligent disk controller responds to a request to store a packet of data by determining which storage location of the rotating disk memory are available and by selecting from among the available locations a location that can be accessed in a minimum amount of time relative to access time of any other available location. The intelligent disk controller makes its selection dynamically by monitoring the current position of the recording head of the rotating disk memory and by searching a record of available locations to select an optimal location. The intelligent disk controller then stores the packet of data on the rotating disk memory. By optimizing such data write operations, the indirectly accessed disk storage device also effectively optimizes data read operations. The indirectly accessed disk storage device also improves disk performance by reshuffling data stored on the rotating disk memory according to these policies during idle periods.
